Spark plugs for M50, 52, 54 series engines

Hey guys, I'm a gonna do some DIY over the weekend and going to change my spark plugs. I'm currently on Bosch Super4 and was wondering if I should stick to the Super4 or try some of those new fangled Iridium thingies and such. Or maybe Golden Lodge? Or Splitfire?What are you guys using anyway? Do share your experience.

Stick to the Bosch or the OEM plugs. I am currently using the multi point plugs bought from 911 Zentrum (forgot the name leow), but did not notice significant increase in performance.I believe the direct ignition system with individual coils system employed by BMW is providing more than sufficient spark to the plugs. Anything more, is akin to too much of a good thing.Al

No wonder lah. The Bosch Super4 that i'm using now does not make a difference compared to the regular Bosch the car came with. How often do you change your plugs anyway?

Whenever Inspection II is due.

Some love Iridium plugs. YMMV.
